My next question is: How the Devil do you get one apart?
At first glance it appears that two setscrews would allow the the bottom
of the antenna to come off it two pieces, not counting the long sleeve
that holds the mast clamps and covers the coax connector. Unfortunately
it looks like those remaining pieces are also epoxied on. I've managed
to heat them quite hot with a heat gun and nothing melted. I didn't
want to get them any hotter for fear of damaging the fiberglass. I've
found bottom sections for sale that included the matching section and
it's listed that way in the parts list. The very bottom end has a small
ring at the top with a set screw. This has to come off before the ring
that holds the radials can come off.
